Sintered silicon carbide ceramics ndi silicon carbide ceramic bulletproof product series

Sintered SiC Ceramics: Ubwino wa SiC Ceramic Ballistic Products

Silicon carbide ceramic bulletproof mankhwalaakuchulukirachulukirachulukira m'munda wachitetezo chaumwini ndi chankhondo chifukwa cha magwiridwe antchito awo abwino kwambiri. Ma Ceramics awa ali ndi SiC ≥99% ndi kuuma (HV0.5) ≥2600, kuwapanga kukhala zinthu zosankhidwa pamasewera a ballistic monga ma vests oteteza zipolopolo ndi zida zodzitchinjiriza za akasinja ndi magalimoto okhala ndi zida.

Chogulitsa chachikulu cha mndandandawu ndi pepala la silicon carbide ceramic bulletproof sheet. Kuchepa kwake komanso kulemera kwake kopepuka kumapangitsa kuti ikhale yoyenera kwambiri kwa msilikali aliyense payekhapayekha zida zoteteza zipolopolo, makamaka ngati mizere yamkati ya ma vests oteteza zipolopolo. Kuphatikiza apo, imapereka maubwino ofunikira pakukhazikika, mphamvu komanso kukhazikika kwamafuta.

Silicon carbide (SiC) ceramics ali ndi zida ziwiri za crystal, cubic β-SiC ndi hexagonal α-SiC. Ma Ceramics awa ali ndi zomangira zolimba za covalent, makina abwinoko, kukana kwa okosijeni, kukana kuvala komanso kukangana kochepa kuposa zoumba zina monga alumina ndi boron carbide. Kutentha kwawo kwakukulu, kocheperako pang'ono kwa kukula kwa matenthedwe, komanso kukana kwambiri kugwedezeka kwa kutentha ndi kuwonongeka kwa mankhwala kumawathandizanso ntchito zawo zosiyanasiyana.

Mfundo yopanda zipolopolo ya silicon carbide ceramics yagona pakutha kwake kuwononga ndi kuyamwa mphamvu za zipolopolo. Ngakhale zida zamaumisiri azikhalidwe zimatengera mphamvu kudzera mukusintha kwa pulasitiki, zida za ceramic, kuphatikiza silicon carbide, zimatero kudzera mu ma microfractures.

Njira yoyamwitsa mphamvu ya silicon carbide bulletproof ceramics ikhoza kugawidwa m'magawo atatu. Pa gawo loyambirira, chipolopolocho chimagunda pamwamba pa ceramic, ndikuchotsa chipolopolocho ndikuphwanya pamwamba pa ceramic, ndikupanga madera ang'onoang'ono ogawanika. Panthawi ya kukokoloka, chipolopolo chosawoneka bwinocho chikupitilira kuwononga malo a zinyalala, ndikupanga kusanjikiza kosalekeza kwa zinyalala za ceramic. Pomaliza, panthawi yopindika, ming'alu ndi kusweka, ceramic imakumana ndi zovuta, zomwe zimatsogolera kuphulika kwake. Mphamvu yotsalayo imatayidwa ndi mapindikidwe a zinthu zakumbuyo.

Zinthu zabwinozi komanso njira zoyamwitsa mphamvu zamagawo atatu zimathandiza kuti zinthu za silicon carbide ceramic ballistic zichepetse mphamvu ya zipolopolo ndikuzipanga kukhala zopanda vuto. Chiwopsezo cha zipolopolo chimafika mulingo wa 4 waku America, womwe umapereka chitetezo chokwanira komanso chisankho choyamba cha akatswiri ankhondo padziko lonse lapansi.

Mwachidule, zoumba za sintered silicon carbide ceramics ndi silicon carbide ceramic bulletproof product series zili ndi maubwino apadera malinga ndi makina, kukhazikika kwamafuta, komanso kutetezedwa kwa zipolopolo. Ndi katundu wawo wapamwamba, zoumbazi zimagwiritsidwa ntchito kwambiri ngati zida zomangira zipolopolo zotchingira zipolopolo ndi zida zotetezera akasinja ndi magalimoto okhala ndi zida. Kuchepa kwawo komanso kulemera kwawo kopepuka kumawapangitsa kukhala abwino pachitetezo chamunthu. Pamene ukadaulo ukupitilirabe kupita patsogolo, titha kuyembekezera kupititsa patsogolo komanso kugwiritsa ntchito zida zadothi zodabwitsazi pachitetezo chamunthu komanso chankhondo.
